Given: A customer purchased 6 shirts priced at $10.99 each, excluding sales tax.
So, the total price of the shirts (excluding sales tax) =
(6)($10.99)
Target question: How much sales tax did he pay on this purchase?
Statement 1: The customer paid a 5 percent sales tax on the total price of the shirts.
So the sales tax = 5% of
(6)($10.99)
Since we COULD evaluate 5% of
(6)($10.99), we COULD answer the
target question with certainty
(although we would never waste valuable time doing so on test day!)
Statement 1 is SUFFICIENT
Statement 2: The customer paid a total of $11.54 for each shirt, including sales tax
So, the sales tax on ONE shirt = $11.54 - $10.99 = $0.55
So,
the sales tax on all 6 shirts = (6)($0.55)
Since we can answer the
target question with certainty, statement 2 is SUFFICIENT
Answer: D
